Above you can see the measurement of the evalboard with a span of 100 MHz.
The evalboard has been optimized for 3 V. The load is about 700+j0
the transmit frequency.
A tuning-free realization requires a careful design of the components within the
matching network. A simple linear CAE-tool will help to see the influence of
tolerances of matching components.
Suppression of spurious harmonics may require some additional filtering within
the antenna matching circuit. The total spectrum of a typical 50
testboard can be summarized as:
